论数字化学术期刊

学术期刊数字化、网络化已经成为网络上很普遍的存在。大量充斥因特网的学术期刊网页、网站,看似繁华,其实,它的生存状态很艰难。即使目前学术期刊通过网页或是网站参与学术资源的传递,也只是在原有期刊工作模式下的一些补充,还不能被视为“网络期刊”。数字化学术 解决的问题很多,包括谁来的数字化运作付费、平面期刊网络化的技术、学术资源检索的工具和检索模式的合理化等,只有突破这些“瓶颈”问题,学术期刊的数字化才会真正取得进展。     

An Adaptive Finite Element Method Based on OptimalError Estimates for Linear Elliptic Problems

The subject of the work is to propose a series of papers about adaptive finite element methods based on optimal error control estimate. This paper is the third part in a series of papers on adaptive finite element methods based on optimal error estimates for linear elliptic problems on the concave comer domains. In the preceding two papers (part 1 : Adaptive finite element method based on optimal error estimate for linear elliptic problems on concave comer domain; part 2:Adaptive finite element method based on optimal error estimate for linear elliptic problems on nonconvex polygonal domains), we presented adaptive finite element methods based on the energy norm and the maximum norm. In this paper, an important result is presented and analyzed. The algorithm for error control in the energy norm and maximum norm in part 1 and part 2 in this series of papers is based on this result.     

Elementary and Secondary School Counselor Preparation Programs: How Different are They?

There is a paucity of current information on training programs for elementary school counselors. Also, criticisms about roles and the need for specialized training for this group are contained in recent literature. This article presents the results of a national survey that focused on the differences in preparation programs for elementary and secondary school counselors. Data on specific courses and number of required courses for elementary and for secondary counselors are included.     

Testing and Motivation for Learning

This paper presents the procedures and findings of a systematic review of research on the impact of testing on students' motivation for learning. The review was undertaken to provide evidence in relation to claims that, on the one hand, testing raises standards and, on the other, that testing, particularly in high stakes contexts, has a negative impact on motivation for learning that militates against preparation for lifelong learning. Motivation is considered as a complex concept, closely aligned with 'the will to learn', and encompassing self-esteem, self-efficacy, effort, self-regulation, locus of control and goal orientation. The paper describes the systematic methodology of the review and sets out the evidence base for the findings, which serve to substantiate the concern about the impact of summative assessment on motivation for learning. Implications for policy and practice are drawn from the findings.     

Comparing balance and inverse methods on learning conceptual and procedural knowledge in equation solving: a cognitive load perspective

We examined the use of balance and inverse methods in equation solving. The main difference between the balance and inverse methods lies in the operational line (e.g. +2 on both sides vs ?2 becomes +2). Differential element interactivity favours the inverse method because the interaction between elements occurs on both sides of the equation for the balance method but only on one side of the equation for the inverse method. In an experimental study, 63 students (mean age = 13) were randomly allocated to either balance or inverse group to undertake a pre-test, study an instruction sheet, complete acquisition equations, sit for a post-test and a concept test. Procedural knowledge was assessed on performance on practice equations and post-test, whereas conceptual knowledge was assessed on performance on the concept test. The inverse group outperformed the balance group on practice equations but not the post-test. Both the balance and inverse groups scored higher on the inverse concept test than the balance concept test. Positive association between performance on procedural knowledge and performance on conceptual knowledge was found for the inverse group but not the balance group. Overall, the evidence obtained indicates a number of educational implications for implementation.

晶体电光调制及通信观测分析

晶体电光调制实验通常在测量半波电压的基础上,进而观测线性区音频信号传输特性。尽管线性区是实际应用的选择区域,但是非线性区的实验现象却丰富了实验教学内容及有助于进一步理解实验物理原理。通过对传统教学设备技术改造并配合利用计算机标配资源实现了全区域的实验现象观测和实验结果深入分析,也体现了实践层次化物理实验教学改革的可行途径。     

钦州学院生化系专业结构调整与拓展的思考——以化学专业调整为例

地方高校定位和广西临海化工产业群的建设与发展,使钦州学院生化系调整专业结构,面向临海化工产业拓展专业领域,既是必要的,也是可行的.但必须冷静面对地方化工产业迅速发展对生化系扩张发展的要求与生化系原有基础薄弱这一矛盾,探索切实可行的超常规发展的办法.生化系应该走利用自身基础滚动发展与充分利用临海化工产业发展的优势调动各方力量加快生化系发展相结合的道路.随着生化系办学基础的充实以及临海化工产业群的形成,日后的生化系应探索一条高校与企业合作办学的路子,以促进产学研的结合,最大限度地落实地方高校为地方经济服务的办学定位目标.

语法本体研究与对外汉语语法教学

本文认为汉语语法本体研究跟对外汉语语法教学之间的关系,应该是“双向互动”的.一方面汉语语法研究必须结合对外汉语语法教学注重句法的语义分析,另一方面也必须从对外汉语语法教学中发现问题并吸取灵感;至于对外汉语语法教学,需要从汉语语法研究中吸取营养,而且在引入语法本体研究成果时必须化繁为简、为我所用.

“中职硕士”是为中等职业学校教师在职攻读硕士学位而设置的一种新型的职业型学位,旨在培养中等职业学校高层次“双师型”教师,属于目前专业学位教育范畴。我国目前的中职硕士培养尚存在生源差异较大等问题,应借鉴国内外经验,设立一种新的专业学位,即“职业技术教育硕士”。     

大学基础课成绩对专业课成绩的影响

运用多元统计中的典型相关分析法,分析了大学生基础课成绩对专业课成绩的影响,得出的结论是:计算机和概率统计课程对专业课中的统计软件课以及各种统计类课程有较大影响,微积分和英语对西方经济学及双语教学类课程有中等程度的影响,基础课中的法律、思想政治及体育课对专业课几乎没有显著影响。     

英汉名词修饰语语序对比研究及其认知分析

英汉两种语言在语序上具有某种程度的共性,这是我们进行英汉语序对比的基础。英汉两种语言在名词修饰语顺序上有共性也有相异性。这既可为人类语言类型学的研究提供左证,也为解释人类共有的认知机制尤其是语言上所映射的人类认知选择及先后和人的信息处理能力与机制提供了认识的窗口。     

现代技术伦理规约的困境及其消解

通过对现代技术伦理规约的责任困境和科林格里奇控制困境的分析,可以揭示技术伦理规约的过程本质。现代技术伦理规约的本质不仅仅是对技术主体、技术客体的规约,而是对技术主体与技术客体相统一的动态过程的伦理规约,是在技术-伦理开放框架内的协同与整合,由此可以消解技术伦理规约的困境。     

教育技术学科点建设的系统分析和发展策略

从系统工程的思想和方法的视角,将学科点的建设问题看作是一个具有多种目标变量、控制变量和环境变量的系统优化问题,可以把影响学科点建设的因素分为三类:学科产出(目标变量)、学科状态(控制变量)和学科环境(环境变量),将学科点的发展策略视作对上述系统的动态控制手段。通过采用案例分析的方法,对基于上述系统模型结合国内外三个教育技术学科点的发展状况和策略进行了分析,结果表明:该系统模型较好地说明了教育技术学科点建设中各种影响因素之间的关系以及学科点特色形成的机制,据此归纳总结了教育技术学科点的发展策略。     

A critical review of the role of texts in fostering Intercultural Communicative competence in the English Language classroom

This review maps and critically evaluates 36 empirical studies from English language teaching (ELT), focusing on the role of texts and activities in intercultural learning. The rationale for this review is the call for theoretically-based recommendations for English language (EL) teachers and researchers on the selection of texts and the design of activities for intercultural learning. It draws on principles from Critical Interpretive Synthesis (CIS), and the studies were gathered from systematic searches of databases, supplemented by manual searches of relevant journals. The results show that fiction texts are more widely used and more strongly rationalized for use than nonfiction texts. There is also a strong focus on dialogic and student-centred activities, and less focus on experiential teaching. It argues that an awareness of the affordances of different text types can assist teachers in mediating EL students’ intercultural learning and recommends a greater variety of research and teaching approaches to identify intercultural learning processes. Furthermore, the review calls for more research on intercultural learning in primary and secondary ELT.
